Turbulence is everywhere, yet much about the nature of turbulence remains unknown. During the last decade, physicists have discovered how fluids in a pipe or similar geometry transition from a smooth, laminar state to a turbulent ...
Abiotic organic synthesis during geological processes has long drawn scientific interest, as it is believed to have laid both the material and energetic groundwork for the emergence of early life on Earth.
The composition of sweat makes it a valuable diagnostic fluid. While it is mostly water, the small fraction containing electrolytes, metabolic byproducts, and chemical traces can reveal important information about a person's ...
Researchers at the University of Illinois Urbana-Champaign have developed a novel framework for understanding and controlling the flow behavior of granular hydrogels—a class of material made up of densely packed, microscopic ...
In 1951, physicist Julian Schwinger theorized that by applying a uniform electrical field to a vacuum, electron-positron pairs would be spontaneously created out of nothing, through a phenomenon called quantum tunneling.
For several decades, a central puzzle in quantum physics has remained unsolved: Could electrons behave like a perfect, frictionless fluid with electrical properties described by a universal quantum number?
Summertime is beer time—even if the consumption of alcoholic beer is declining in Switzerland. And for beer lovers, there is nothing better than a head of foam topping the golden, sparkling barley juice. But with many beers, ...
Regulating the flow of protons across the chloroplast and modulating the activity of its CFo-CF1 adenosine triphosphate (ATP) synthase protein are key to protecting plants from excessive light energy absorbed during photosynthesis, ...
In everyday life, all matter exists as either a gas, liquid, or solid. In quantum mechanics, however, it is possible for two distinct states to exist simultaneously. An ultracold quantum system, for instance, can exhibit ...
Plants have a sophisticated internal communication system to help them optimize energy production. Now, a new study by an international team of scientists led by Penn State researchers reveals for the first time the molecular ...
